Objects (Devil May Cry 4)

Vanishing Floor
Vanishing Floors are found in the Mitis Forest, and are used to gain access to areas not accessible by foot. The floors serve as bridges across gaps, but disappear shortly after being stepped on, or at a set time limit. When the floor panel flashes red, it is just about to disappear.

They are extraordinarily similar to the Appearing Blocks which appear in CAPCOM's Mega Man series.
